(57) A pointing device for moving a display pointer by tilting a center shaft including a magnet and using Hall elements fixed near the magnet. The center shaft is sustained by a pivot sustainer fixed on a central axis of the device, and the tilting movement of the center shaft is changed to movement made along the central axis by a movement converting mechanism using spring force, for moving the magnet back on the central axis when the center shaft is freed from tilting.
